Abstract

The invention discloses an anti-die-drawing insert structure of a die. The die is provided with a core insert and a cavity insert for forming a product, and one side of the product is provided with a bore column, and the anti-die-drawing insert structure is characterized by comprising an insert trough and a movable insert, wherein the insert trough is arranged in the core insert, and one side of the insert trough is provided with a hanging boss groove; and the movable insert is movably arranged in the insert trough, the top end of the movable insert cooperatively forms the bore column, the bottom end of the movable insert is provided with the hanging boss, and the height of the hanging boss is less than that of the hanging boss groove. In the process of die sinking, the product drives the movable insert to move together by virtue of a die sticking force, and because at the moment, the movable insert does not need to be separated from the product, in the process of ejection, the die sticking force between the product and the core insert only needs to be overcome, no die drawing is caused, and an ejector pin is not invalidly ejected. When the die sinking continues to be performed, the hanging boss of the movable insert is limited in the hanging boss groove, and stops moving, but the product continues to be ejected, and the movable insert is gradually separated from the bore column.

Description

The anti-drawing-die of mould enters minor structure
[technical field]
The present invention relates to a kind of anti-drawing-die and enter minor structure, the anti-drawing-die being specifically related to a kind of mould enters minor structure.
[background technology]
Refer to Fig. 1, Fig. 1 is a kind of sectional structure schematic diagram of product.Product 100 as shown in the figure, its side has hole post 101.Because described hole post 101 can bond, be difficult to depart from its forming surface shaping, so the forming surface of shaping described hole post 101 can not be located at mother module core, and must be located in male die core, but easily causing drawing-die when adopting thimble to eject described product 100, thimble easily pushes up white.
The mould sectional structure schematic diagram for product shown in Fig. 1 is illustrated referring again to Fig. 2, Fig. 2.Described mould has male die core 103 and the mother module core 104 of shaping described product 100, described male die core 103 also has shaping described product 100 hole post 101 outer peripheral portion, also have in described male die core into pilot trench 102, describedly enter to have in pilot trench 102 into son 105, described in enter the bore section that sub 105 tops have shaping described hole post 101.When ejecting described product 100, because the hole post 101 of described product 100 also can have very large sticking to mould power, when therefore ejecting, meeting drawing-die, easily causes thimble (not shown) top white.
In view of this, be necessary that the anti-drawing-die providing a kind of mould enters minor structure, to solve the problem in fact.
[summary of the invention]
Therefore, the anti-drawing-die that the object of this invention is to provide a kind of mould enters minor structure, solves prior art and adopts mould to carry out shaping for the product with Kong Zhu, the problem of easy drawing-die during die sinking.
In order to achieve the above object, the anti-drawing-die of mould of the present invention enters minor structure, and this mould has male die core and the mother module core of shaped article, and this anti-drawing-die enters minor structure and comprises:
Enter pilot trench, be located in described male die core, described in enter pilot trench side there is hanging platform groove;
Activity enters son, movable be located at described in enter in pilot trench, described activity enters sub-bottom and has hanging platform, and the height of described hanging platform is less than the height of described hanging platform groove.
Optionally, described activity enter son and described enter coefficient of friction between pilot trench wall little.
Compared to prior art, the anti-drawing-die of mould of the present invention enters minor structure, during die sinking, described product relies on sticking to mould power to drive described activity to enter son and moves together, because now described activity enters son without the need to being separated with between product, be only the mucous membrane power overcome between described product and described male die core when ejecting, can not cause drawing-die, thimble can not push up white.Continue die sinking, then the described hanging platform that described activity enters son is limited to described hanging platform groove, stop motion, and described product can continue to eject, and described activity enters son and is separated gradually with the described Kong Zhu of described product.
[accompanying drawing explanation]
Fig. 1 is a kind of sectional structure schematic diagram of product.
Fig. 2 illustrates the mould sectional structure schematic diagram for product shown in Fig. 1.
The anti-drawing-die that Fig. 3 illustrates as mould of the present invention enters minor structure one preferred embodiment matched moulds status architecture schematic diagram.
The anti-drawing-die that Fig. 4 illustrates as mould of the present invention enters minor structure one preferred embodiment first die opening state structural representation.
The anti-drawing-die that Fig. 5 illustrates as mould of the present invention enters minor structure one preferred embodiment and die opening state structural representation.
[detailed description of the invention]
Refer to Fig. 3, the anti-drawing-die that Fig. 3 illustrates as mould of the present invention enters minor structure one preferred embodiment matched moulds status architecture schematic diagram.
In order to achieve the above object, the anti-drawing-die of mould of the present invention enters minor structure, and this mould has male die core 201 and the mother module core 202 of shaped article 207, and described product 207 side has hole post 208, and this anti-drawing-die enters minor structure and comprises:
Enter pilot trench 203, be located in described male die core 201, described in enter pilot trench 203 side there is hanging platform groove 204;
Activity enters son 205, movable be located at described in enter in pilot trench 203, described activity enters sub 205 tops and coordinates shaping described hole posts 208, and described activity enters sub 205 bottoms and has hanging platform 206, and the height of described hanging platform 206 is less than the height of described hanging platform groove 204.
Wherein, described activity enter son 205 and described enter pilot trench 203 wall between coefficient of friction little, thus activity of stating described in can making enters son 205 and describedly enters mutually to move between pilot trench 203 smooth and easy, avoids hindering described product 207.
Please combine again and consult Fig. 4, the anti-drawing-die that Fig. 4 illustrates as mould of the present invention enters minor structure one preferred embodiment first die opening state structural representation.
During die sinking, described product 207 relies on sticking to mould power to drive described activity to enter son 205 and moves together, because now described activity enters son 205 without the need to being separated with between product 207, only overcome the mucous membrane power between described product 207 and described male die core 201 when ejecting, can not cause drawing-die, thimble (not shown) can not be pushed up white.
Refer to Fig. 5, the anti-drawing-die that Fig. 5 illustrates as mould of the present invention enters minor structure one preferred embodiment and die opening state structural representation.
Continue die sinking, then the described hanging platform 206 that described activity enters son 205 is limited to described hanging platform groove 204, stop motion, and described product 207 can continue to eject, and described activity enters son 205 and is separated gradually with the described hole post 208 of described product 207.
